Riser assembly for hairdressing chair

Abstract

A riser assembly for a chair with a base normally reposed on a floor surface, comprising a base having a series of circumferentially spaced-apart retention openings in a peripheral portion thereof, and a foot rest associated therewith. The foot rest has legs of a size to be insertable into the openings in the riser base peripheral portion, to position the foot rest on the riser base, and a bearing member joined to the platform and engaging a chair base as positioned on the riser base, to support the platform in an upwardly inclined position. The riser assembly has utility as a support structure for hairdressing and similar chairs, permitting a standing person servicing an individual seated in the chair to assume standing positions which reduce or eliminate stress and fatigue.

       1. A riser assembly for a chair with a base normally reposed on a floor surface, comprising: (a) a riser base having a top surface for supporting a said chair base thereon;   (b) a series of circumferentially spaced-apart retention openings in a peripheral portion of said riser base; and   (c) a foot rest, comprising: (i) a supporting platform;   (ii) legs joined to a first end of said platform, said legs being of a size to be insertable into said openings in said riser base peripheral portion, to position said foot rest on said riser base; and   (iii) a bearing member, joined to said platform and engageable with a said chair base as positioned on said riser base, to support said platform in an upwardly inclined position.     
     
     
       2. A riser assembly according to claim 1, comprising an upstanding ridge member extending circumferentially around a peripheral portion of said riser base on said top surface thereof, for laterally retaining a said chair base on said riser base. 
     
     
       3. A riser assembly according to claim 2, wherein said retention openings are in said ridge member. 
     
     
       4. A riser assembly according to claim 1, in which said bearing member is integrally formed with said platform, and comprises a flanged portion depending downwardly from a second end of said platform. 
     
     
       5. A riser assembly according to claim 1, wherein said platform has a length of from about 4 to about 10 inches.
